[0001] The present invention relates to benzimidazolyl-methyl urea derivatives of formula
(I) and their use as pharmaceuticals. The invention also concerns related aspects
including processes for the preparation of the compounds, pharmaceutical compositions
containing one or more compounds of formula (I), and especially their use as ALX receptor
agonists.
[0002] ALXR (alias Lipoxin A4 Receptor, FPRL1, FPR2; disclosed in
WO2003/082314 as nucleotide sequence SEQ ID NO:1 and amino acid sequence SEQ ID NO:2) is a member
of the G-protein coupled receptor family. ALXR was found to mediate calcium mobilization
in response to high concentration of the formyl-methionine-leucyl-phenylalanine peptide.
Furthermore, a lipid metabolite, lipoxin A4 (LXA4), and its analogues, were found
to bind ALXR with high affinity and increase arachidonic acid production and G-protein
activation in ALXR transfected cells (
Chiang et al., Pharmacol. Rev., 2006, 58, 463-487). The effects of LXA4 have been evaluated in a variety of animal models of diseases;
and LXA4 was demonstrated to have potent anti-inflammatory and pro-resolution activities.
The disease models where LXA4, or derivatives, or stable analogs, demonstrated
in vivo activities are for example dermal inflammation, dorsal air pouch, ischemia/reperfusion
injury, peritonitis, colitis, mesangioproliferative nephritis, pleuritis, asthma,
cystic fibrosis, sepsis, corneal injury, angiogenesis, periodontitis, carrageenan-induced
hyperalgesia, and graft-vs-host disease (GvHD) (
Schwab and Serhan, Current Opinion in Pharmacology, 2006, 414-420). Lipoxin A4 inhibited IL-6 expression in human fibroblast-like synoviocytes (
Sodin-Semrl et al, Int J Immunopathol Pharmacol (2004) 17:15-25) and a stable FPR2 agonist, BML-111, reduced the severity of collagen-induced arthritis
(
Zhang et al., (2008) Inflamm Res 57:157-162) demonstrating a possible use of FPR2 agonists in the treatment of rheumatoid arthritis.
Mice with acute lung injury (ALI) showed reduced pulmonary inflammation when treated
with stable lipoxin A4 (
Jin et al., (2007) Anesth Analg 104:369-377). Lower lipoxin A4 levels in severe asthma (
Celik et al., (2007) Clin Exp Allergy 37:1494-1501;
Planaguma et al, (2008) Am J Respir Crit Care Med 178:574-582) and improvement of asthma responses in animal models by stable lipoxin A4 analogs
(
Levy et al., (2002) Nat Med 8:1018-1023;
Levy et al., (2007) FASEB J 21:3877-3884) have been described. In cystic fibrosis it was shown, that the levels of pulmonary
lipoxin A4 are decreased both in the lung of cystic fibrosis patients and in animal
models of the disease (
Karp et al., (2004) Nat Immunol 5:388-392); treatment with a stable lipoxin analog improved inflammatory cell accumulation
within the diseased lung and reduced body weight loss in the same animals (
Karp et al., (2004) Nat Immunol 5:388-392). Topical treatment with lipoxin A4 increases re-epithelization and decreases inflammation
of the dry corneal surface (
Gronert, (2005) Prostaglandins Leukot Essent Fatty Acids 73:221-229;
Gronert et al., (2005) J Biol Chem 280:15267-15278) demonstrating a possible use of FPR2 agonists in the treatment of keratoconjunctivitis
sicca. Oral administration of lipoxin A4 analogs reduced the severity of colitis in
a mouse model of inflammatory bowel disease (
Gewirtz et al., (2002) Eicosanoids and other Bioactive Lipids in Cancer, Inflammation,
and Radiation Injury, Kluwer Academic/Plenum Publishers, 229-236). ALXR was also identified as a functional receptor of a various number of peptides,
including a fragment of the prion protein, a peptide derived from gp120 of the Human
Immunodeficiency Virus (HIV)-1
LAI strain, and amyloid-beta 1-42 (Ab42) (for review,
Le et al., Protein Pept Lett., 2007, 14, 846-853), and has been suggested to participate in the pathogenesis of Alzheimer's Disease
(AD) in several crucial ways (
Yazawa et al., FASEB J., 2001, 15, 2454-2462). Activation of ALXR on macrophages and microglial cells initiates a G protein-mediated
signaling cascade that increases directional cell migration, phagocytosis, and mediator
release. These events may account for the recruitment of mononuclear cells to the
vicinity of senile plaques in the diseased areas of AD brain where Ab42 is overproduced
and accumulated. Although accumulation of leukocytes at the sites of tissue injury
may be considered an innate host response aimed at the clearance of noxious agents,
activated mononuclear phagocytes also release a variety of substances such as superoxide
anions that may be toxic to neurons. Thus, ALXR may mediate pro-inflammatory responses
elicited by Ab42 in AD brain and exacerbate disease progression. Further, humanin
is a high-affinity ligand for FPR2 and is neuroprotective in models of Alzheimer's
Disease (
Mamiya et al., (2001) Br J Pharmacol 134:1597-1599;
Ying et al., (2004) J Immunol 172:7078-7085;
Miao et al., (2008) Neuropeptides 42:557-567).
[0003] The biological properties of ALXR agonists include, but are not limited to, monocyte/macrophage/microglia/dendritic
cell migration/activation, neutrophil migration/ activation, regulation of lymphocyte
activation, proliferation and differentiation, regulation of inflammation, regulation
of cytokine production and/or release, regulation of proinflammatory mediator production
and/or release, regulation of immune reaction.
[0004] The present invention provides benzimidazolyl-methyl urea derivatives, which are
non-peptide agonists of human ALX receptor. Other urea derivatives with agonistic
activity on human ALX receptor have been disclosed in
WO2005/047899,
WO2013/062947,
WO2013/070600 and
WO2013/071203. Different benzimidazolyl-methyl derivatives have been disclosed in
WO2003/076432,
WO2004/007459 and
WO2005/035551 which are used as CGRP receptor antagonists, vanilloid VR1 receptor modulators and
phosphatase modulators, respectively. The compounds are useful for the prevention
or treatment of diseases, which respond to the modulation of the ALX receptor such
as inflammatory diseases, obstructive airway diseases, allergic conditions, HIV-mediated
retroviral infections, cardiovascular disorders, neuroinflammation, neurological disorders,
pain, prion-mediated diseases and amyloid-mediated disorders (especially Alzheimer's
disease); in addition they are useful for the prevention or treatment of autoimmune
diseases and for the modulation of immune responses (especially those elicited by
vaccination).

[0006] The compounds of formula (I) according to embodiment 1) may contain one or more stereogenic
or asymmetric centers, such as one or more asymmetric carbon atoms. Substituents at
a double bond may be present in the (
Z)- or (
E)-configuration unless indicated otherwise. The compounds of formula (I) may thus
be present as mixtures of stereoisomers or preferably as pure stereoisomers. Mixtures
of stereoisomers may be separated in a manner known to a person skilled in the art.
[0007] In this patent application, variably attached bonds may be used for substituents
or groups. In such case it is meant that the substituent or group is attached to any
carbon atom of the ring system to which the variable attached bond is drawn into,
provided that said carbon atom is not already specifically substituted. For example,
it is understood that any group
R9 may be attached to any carbon atom of the phenyl ring of formula (I) which is not
already substituted. In case n represents 1, formula (I) therefore encompasses the
following two formulas:

[0008] In case n represents 2, the second
R9 group may be attached to any carbon atom of the phenyl ring of any one of formulas
(I-1) or (I-2), which carbon atom is not already substituted, wherein the two
R9 groups may be the same or different. Cases, wherein
n represents 3 or 4 are construed in analogy. In case
n represents 0, the
R9 group is absent.
[0009] Further, it is well known in the art that benzimidazole derivatives may be present
in different tautomeric forms. Examples of such tautomers are given in formulas (I-T1)
and (I-T2) below:

[0010] It is to be understood that in any such case both tautomers are within the scope
of the present invention. Even though one tautomer may be described, the present invention
includes both tautomers of the present compounds. Especially, any given chemical name
does represent not only the specifically named chemical compound but also the different
tautomeric form thereof. In solution, tautomers exist usually as mixtures of different
tautomeric forms; in the solid state usually one tautomeric form predominates.
[0011] For avoidance of any doubt, especially with respect to any stereogenic center, compounds
of formula (I) are denominated in analogy to the following examples:
- i. in case a compound is present as a pure stereoisomer, having a defined configuration
at each stereogenic center present, the compound is denominated in accordance with
the (R)-/(S)-nomenclature; for example, the pure stereoisomer of structure

is denominated (R)-1-(1-(1H-benzo[d]imidazol-2-yl)-2-(4-methoxyphenyl)ethyl)-3-(1,5-dimethyl-1 H-pyrazol-3-yl)urea;
- ii. in case a compound is present as a mixture of stereoisomers, wherein one or more
stereogenic centers are present as a mixture of (R)- and (S)-configurated forms, the
compound is denominated without any label regarding the configuration of any of these
stereogenic centers; for example, a mixture of stereoisomers of structure

is denominated 1-((R)-1-(1H-benzo[d]imidazol-2-yl)-2-(4-methoxyphenyl)ethyl)-3-(1-methoxy-3-phenylpropan-2-yl)urea;
- iii. in the special case of case ii), wherein a compound is present as a mixture of
stereoisomers with known relative configuration of two stereogenic centers (but unknown
absolute configuration), the compound is denominated using an asterisk together with
the (R)-/(S)-nomenclature with respect to these two stereogenic centers; for example,
a mixture of trans-diastereoisomers of structure

is denominated (1R*,2R*)-ethyl 2-(3-((R)-1-(1 H-benzo[d]imidazol-2-yl)-2-(4-methoxyphenyl)ethyl)ureido)cyclohexanecarboxylate;
and
- iv. in the special case, wherein a compound is present as a pure stereoisomer obtained
from separation of a mixture by chiral HPLC chromatography, such that the absolute
configuration of one or more stereogenic centers is unknown, the compound is denominated
without any label regarding the configuration of any of the unknown stereogenic centers;
instead, the suffix "(ent-1)" is used for the first eluting stereoisomer and the suffix
"(ent-2)" is used for the second eluting stereoisomer; for example, the first eluting
stereoisomer obtained from chiral HPLC separation of a mixture of 1-(1-(1H-benzo[d]imidazol-2-yl)-2-(4-methoxyphenyl)ethyl)-3-(1,5-dimethyl-1H-pyrazol-3-yl)urea is denominated "1-(1-(1H-benzo[d]imidazol-2-yl)-2-(4-methoxyphenyl)ethyl)-3-(1,5-dimethyl-1H-pyrazol-3-yl)urea (ent-1)" and the second eluting stereoisomer from that mixture
is denominated "1-(1-(1H-benzo[d]imidazol-2-yl)-2-(4-methoxyphenyl)ethyl)-3-(1,5-dimethyl-1H-pyrazol-3-yl)urea (ent-2)";
[0012] For avoidance of any doubt, a "pure stereoisomer" (or alternatively "pure enantiomer"),
as used in the description and the claims, contains less than 10%, preferably less
than 3% and most preferably less than 1% of another stereoisomer (or the sum of other
stereoisomers in case more than one other stereoisomer is possible).

[0118] The present invention also includes isotopically labelled, especially
2H (deuterium) labelled compounds of formula (I), which compounds are identical to
the compounds of formula (I) except that one or more atoms have each been replaced
by an atom having the same atomic number but an atomic mass different from the atomic
mass usually found in nature. Isotopically labelled, especially
2H (deuterium) labelled compounds of formula (I) and salts thereof are within the scope
of the present invention. Substitution of hydrogen with the heavier isotope
2H (deuterium) may lead to greater metabolic stability, resulting e.g. in increased
in-vivo half-life or reduced dosage requirements, or may lead to reduced inhibition of cytochrome
P450 enzymes, resulting e.g. in an improved safety profile. In one embodiment of the
invention, the compounds of formula (I) are not isotopically labelled, or they are
labelled only with one or more deuterium atoms. In a sub-embodiment, the compounds
of formula (I) are not isotopically labelled at all. Isotopically labelled compounds
of formula (I) may be prepared in analogy to the methods described hereinafter, but
using the appropriate isotopic variation of suitable reagents or starting materials.

[0143] Unless used regarding temperatures, the term "about" (or alternatively "around")
placed before a numerical value "X" refers in the current application to an interval
extending from X minus 10% of X to X plus 10% of X, and preferably to an interval
extending from X minus 5% of X to X plus 5% of X. In the particular case of temperatures,
the term "about" (or alternatively "around") placed before a temperature "Y" refers
in the current application to an interval extending from the temperature Y minus 10
°C to Y plus 10 °C, and preferably to an interval extending from Y minus 5 °C to Y
plus 5 °C. Besides, the term "room temperature" (rt) as used herein refers to a temperature
of about 25°C.
[0144] Whenever the word "between" is used to describe a numerical range, it is to be understood
that the end points of the indicated range are explicitly included in the range. For
example: if a temperature range is described to be between 40 °C and 80 °C, this means
that the end points 40 °C and 80 °C are included in the range; or if a variable is
defined as being an integer between 1 and 4, this means that the variable is the integer
1, 2, 3, or 4.
[0145] The compounds of formula (I) can be manufactured by the methods given below, by the
methods given in the Examples or by analogous methods. Optimum reaction conditions
may vary with the particular reactants or solvents used, but such conditions can be
determined by a person skilled in the art by routine optimisation procedures.

A. Synthesis of final products
[0147] The compounds of formula (I) might be prepared from amino acids of structure 1, wherein
PG represents Boc, following the sequence described below:
- a. coupling of an amino acid of structure 1 with the appropriately substituted o-phenylenediamine (or, in case D and/or E represents =N-, the respective heteroaromatic
analogue) at a temperature about rt in a suitable solvent such as AcCN using standard
amide coupling conditions such as EDC / HOBt / DMAP, or TBTU, or HATU, or PyBOP in
presence of a base such as 4-ethylmorpholine, Et3N or DIPEA followed by cyclization of the resulting product in acidic conditions,
such as in acetic acid at a temperature around 60 to 100 °C.
- b. Protecting group deprotection, for example under acidic conditions, such as HCl
in dioxane, for Boc protecting group or hydrogenation conditions, such as Pd/C - H2, for benzyl or benzyl carbamate protecting group.
- c. Cyclization by treatment of the free base of the aminomethyl-benzimidazole derivative
obtained under b. in THF with 1,1'-carbonyldiimidazole, eventually in presence of
a base such as DIPEA.
- d. Urea formation via treatment with the appropriate amine R7R8NH in the presence of a base such as DIPEA in a solvent such as, for example, THF
or AcCN at rt.
[0148] In case the amine R
7R
8NH contains an additional reactive functional group such as an hydroxy-, an amino-
or a carboxy-group, such group is preferably protected during urea formation and might
be deprotected in a further step to give a compound of formula (I). Hydroxy groups
are preferably protected with silyl based protecting groups such as TBDMS and are
released under conditions such as using TBAF in, for example, THF; amino groups are
preferably protected with Boc and are released under conditions such as HCl in dioxane
or CH
2Cl
2, or using
tert-butyldimethylsilyl trifluoromethanesulfonate in CH
2Cl
2; and carboxy groups are preferably protected as ester (especially methyl- or ethylester)
and are released under basic conditions such as using LiOH in a THF-water solvent
mixture. Especially amino groups might be further substituted by reaction with chloroformate
derivatives in a solvent such as CH
2Cl

II. Biological assays
In vitro assay
[0860] The ALX receptor agonistic activity of the compounds of formula (I) is determined
in accordance with the following experimental method.
Experimental method:
Intracellular calcium measurements:
[0861] Cells expressing recombinant human ALX receptor and the G-protein Gα16 (HEK293-hALXR-Gα16)
were grown to 80% confluency in Growing Medium (GM). Cells were detached from culture
dishes with a cell dissociation buffer (Invitrogen, 13151-014), and collected by centrifugation
at 1'000 rpm at rt for 5 min in Assay Buffer (AB) (equal parts of Hank's BSS (Gibco,
14065-049) and DMEM without Phenol Red (Gibco, 11880-028)). After 60 min incubation
at 37°C under 5% CO
2 in AB supplemented with 1 µM Fluo-4 (AM) (Invitrogen, F14202) and 20 mM HEPES (Gibco,
15630-056), the cells were washed and resuspended in AB. They were then seeded onto
384-well FLIPR assay plates (Greiner, 781091) at 50'000 cells in 70 µl per well and
sedimented by centrifugation at 1'000 rpm for 1 min. Stock solutions of test compounds
were made up at a concentration of 10 mM in DMSO, and serially diluted in AB to concentrations
required for activation dose response curves. WKYMVm (Phoenix Peptides) was used as
a reference agonist. A FLIPR Tetra instrument (Molecular Devices) was operated according
to the manufacturer's standard instructions, adding 4 µl of test compound dissolved
at 10 mM in DMSO and diluted prior to the experiment in assay buffer to obtain the
desired final concentration. Changes in fluorescence were monitored before and after
the addition of test compounds at lex=488 nm and lem=540 nm. Emission peak values
above base level after compounds addition were exported after base line subtraction.
Values were normalized to high-level control (WKYMVm compound, 10 nM final concentration)
after subtraction of the base line value (AB addition).
[0862] Agonistic activities with respect to the ALX receptor (EC
50 values) of exemplified compounds are displayed in Table 1.
